In terms of the price of installing a deck outside our single story home, does it matter what type of ground the deck will cover? Is there an advantage to adding a deck over grass instead of concrete (or vice versa)?
Concrete will have to be removed in order to place a footing, and it shouldn’t matter other than that.
Yes the ground type will cost a little more,specially if you decide to use gravel as a base, it provides numerous benefits, provides weed control, drainage, storage space, support footings, decoration,and more.
